# Circuit vs Circuit Simulator

The clearest difference is review sentiment: Circuit Simulator at 77% against Circuit's 0%. Circuit Simulator also leads on rating (4.7 vs 1.0) and ads (none vs shown). Circuit's advantage is in-app purchases (none vs 8). On price, update cadence, device support and iOS requirement there is nothing between them.

Both are free to download. Circuit Simulator sells 8 in-app purchases, starting at $0.99 per month. Circuit asks for nothing beyond the download.

Circuit Simulator holds the better App Store score, 4.7 against 1.0. That said, the two scores are not equally well evidenced: Circuit Simulator has 93 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 0% of Circuit's written reviews are positive against 77% of Circuit Simulator's.

Circuit ships an update every 5 weeks, Circuit Simulator every 6 weeks. The most recent releases landed on October 12, 2026 and October 27, 2026 respectively.
